Question

I am doing a product insert form in PrimeFaces dialog. My bean’s scope is session. I can insert a product, but when I try to insert another product, the form has previous product’s information. I want to reset form. I tried UIInput but it doesnt work. How can I clear the form?

Answer 1

Just create a new product after saving it and make sure that you’re ajax-updating the form after save.

E.g.

<h:form>
    <h:inputText value="#{productController.product.name}" />
    <h:inputTextarea value="#{productController.product.description}" />
    <h:selectOneMenu value="#{productController.product.category}">
        <f:selectItems value="#{applicationData.categories}" />
    </h:selectOneMenu>
    <p:commandButton value="Save" action="#{productController.save}" update="@form" />
</h:form>

with

public void save() {
    productService.save(product);
    product = new Product();
}

By the way, that kind of bean really doesn’t belong in the session scope. Put it in the view scope.
